Title The missing soft X-ray luminosity in cluster cooling flows


DOI 10.5270/esa-wln0yz5
Author Prof Andrew Fabian
Description Recent X-ray spectra of cluster cooling flows, particularly RGS spectra, have shown that the mass cooling rate is much smaller than previously estimated, with little emission seen from gas cooling below 1 keV. The expected soft X-ray luminosity is missing. Why the inner gas is so cool (20-30 per cent of the virial temperature) yet apparently not cooling is a puzzle, which has ramifications for galaxy formation. We propose deep RGS observations of A2597, A1835 and A1795 to resolve this important problem.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
